DRANAGE FITTING.

Application filed January 6, 1922. Serial No. 527,380.

' at present known to us, Fig. 1 isa central sectional View of ourimproved drainage fixture in assembled relation with a water closet anddrain pipe, the closet and drain pipe being shown in side elevation,partly in section; Fig. 2 is a ifraginentary sectional view, the sectionbeing talren at right angies to that shown in i? 1, and the drain pipeand nipple being shown in elevation; Fig. 3 is a plan view ot thedrainage lib ting detached :trom the closet and Fig. l is a fragmentarysectional View of a coniinon type drainage fitting.

Uur improved fitting; consists of au externally threaded nipple 10,adapted to screwed into a drainage coupling 11 at its lower end andarranged to receive an internally threaded ring 12 on its upper end.rlhis ring 12 is formed with an annular paclrinp' recess 13 in its upper'face and a pair or ears lil which are perforated `at 15, to receivelug` screws 16. rlhe lag screws 16 tasten the closet 1T to the rloor orother support. and also compress packing in the annular recess 13 ashereinafter described. iin annular recess 18, surrounding the drainageopening 19 of the iixture, is adapted to receive the upper end of thenipple 19 and an annular iiange 20, also formed in the lower end of thefixture, is adapted to :dt into the open upper end of the nipple 12.

in the old type of drainage tting now in common use (illustrated in Fie:Ll) an externally threaded nipple 21, held in the drainage coupling atits lower end, is adapted to receive an internally threaded ring 22 onits upper end. In this common type of Fitting a gasket 23 is placedbetween the upper Eace of the ring 22 and the lower 'face of the closetand lag screws 16 are inserted through suitable pertorations in a flangeon the nature, the gasket 23 and ring 22 to fas ten tue fixture to thefloor and compress the gasket 23.

Operation.

When the old type of iitting, illustrated in Fig. 4:, is used it isnecessary to cut oit the nipple 21 at the exact level of the bottom ofthe fixture. lf the nipple is ina-de too -short leakage will occurbetween the ring 22 and the bottoni of the iixture and it said nipple istoo long the iXture will not rest properly on the floor. rlhus, repeatedcutting or substitution of new nipples is frequently necessary with theold type of fittings.

In our improved drainage fitting the nipple 10 is securely fastened atits lower end in the drainage coupling 11 and the ring 12 is screweddown on said nipple until. the lower surace oi said ring* rests upon thefloor Packing 25 is new inserted in the annular recess 13 and thefixture placed with the upper end ot' the nipple 10 enten ing the recess18, ylhe lag1 screws 16 are now used to secure the fixture to the floorand to draw it down upon the packing 25. rl`he packing' 25 is thuscoi'npressed between the outer pe iphery oit the nipple 10 and adjacentsur'aces or' the fixture and ring 12 to insure a water tightjoint. Itwill be readily understood that the nipple 10 may terminate at any levelbetween the upper surface of the ring' 12 and the upper ei;- treinity ofthe recess 18, without affecting the eiiiciency of the joint, so thataccurate cutting; ot this nipple is unnecessary.

lWhile we have illustrated our improved fitting as being used to connecta lixture supported on the 'door with a drainage pipe, it will bereadily understood that the fitting` could be used and is intended foruse with wall fixtures as well.

Having described our invention what we claim as new and desire toprotect by Letters Patent is:

1n a drainage iitting, the combination with a drain pipe and a plumbingfixture having an annular recess ot substantial depth surrounding saiddrainage opening, said fixture being; also formed with a relativelyshallow receptacle for packing, adjacent to said tlrst mentioned recess,of a nipple threaded in said drain pipe and arranged to be contractedtherein and eX- tensble to varying degrees into said recess in theplumbing fixture, ay ring adjustable longitudinally on said nipple,intermedi-ate the ends thereof, an annular packing mem ber disposed :insaid receptacle between said JOHN A. HEALY. ring and fixture andsecuring; means for JAMES H. HEALY.

said ring adapted to maintain said packingA member under compression.

In testimony whereof, We have hereunto l0 signed our names to thisspecification.
